then it's not a chord....if you play chord progressions too fast it merely becomes a melody....just harmonized notes. A chord has to last at least a beat in order for it to be a chord, depending on tempo. And even so, you can play as many 'chords' as you like if you halven the tempo, so if the tempo is 130 bpm, record at 65 and put all the chords you want, but the thing is, even though the tempo is 'half', the frequency of the chords has to be slow enough for them to be chords.
